Why Stethoscopes are Perfect Gifts for Nurses

Why stethoscopes are perfect gifts for nurses

The stethoscope is an acoustic device that amplifies body noises to achieve better perception and therefore the integration of various signs, which are heard mainly in the heart, lungs and abdomen and also called a stethoscope, currently the most widely used stethoscopes are The littmann, is an acoustic device used to hear the internal sounds of the human or animal body.

It is generally used in the auscultation of heart sounds or breath sounds, although sometimes it is also used to objectify bowel sounds or murmurs due to abnormal blood flows in arteries and veins. Examination using the stethoscope is called auscultation. They are part of the semiology of General Medicine up to the various specialties.

These ideas will appeal to the professional, practical and fun side of the healthcare professional in your life. Give a gift (or gifts!) that can be used all year long.

How a Stethoscope Works

The hood or membrane is placed on top of the patient’s body. This bell captures and amplifies the vibrations that arise from the sounds of the organs. This is possible thanks to the shape of the bell (concave) and the thinness of the membrane (to be able to copy and amplify the sounds).

Sound or vibrations travel through the hollow tubes and reach the olives, transmitting them to the ears. The tube is generally made of a thick material to isolate the sounds obtained as best as possible, and that these are not lost on the way. The clinician can listen to the sounds through the headphones, as long as there is no external interference.

What are the Types of Stethoscopes?

There are two types of stethoscopes on the market, acoustic or mechanical and electronic, however this guide will only refer to acoustic ones. Within the acoustic group, two main types can be distinguished: Pinard stethoscopes and binaural or conventional stethoscope.

Binaural or Conventional Stethoscope

Stethoscopes are made up of the following parts that, together, transfer acoustic information from the body surface to the examiner’s ears: It is made up of rubber tubes that end in two olives that adapt to the ear and also these tubes link with another It contains a diaphragm and a bell which amplify the auscultation sounds, it is essential for the correct measurement of blood pressure in conjunction with the sphygmomanometer.

What are the Parts of the Stethoscope?

Olives the use of soft olives improves comfort, seal and durability, these are specially coated to improve lubrication and reduce dust adhesion. Available in both sizes, short and long, in black and gray.

Hose set Includes olives, binaurals and hose, spare parts available only in black. It is important that you keep your computer model in mind for a proper purchase. The hoses can be of one or two volumes depending on the model. The hose is made of PVC (polyvinyl chloride), it does not contain latex or natural rubber.

Bell The bell is a fundamental part of the stethoscope, it is positioned on the part of the patient’s body or on the organ that he wishes to auscultate.

How is its Operation?

It has a membrane and a bell. Either part can be placed on the patient. Both detect the acoustic signals that travel through the air-filled tubes and reach the doctor’s ears. The bell transmits low frequency sounds, it is ideal for listening to the lungs. The membrane, on the other hand, detects high frequencies and allows the heart to be heard. To detect the different frequencies, there are two modes: low frequencies high frequencies

Low Frequencies

If you want to hear low-frequency sounds (traditional bell), you can use the open bell or dual-frequency diaphragm so that it makes very light contact with the skin.

High Frequencies

If you want to hear higher frequency sounds with the dual frequency diaphragm, press the bell firmly. If you want to switch between high and low frequency sounds without having to turn the bell, simply vary the pressure exerted on it.
